How Refractive Index Technology Works
The HI96803 measures glucose content by analyzing how light refracts through your sample. Using a yellow LED light source, precision prism, and linear image sensor, the instrument determines the refractive index and converts it to % glucose by weight according to ICUMSA Methods Book standards for glucose solutions. The built-in temperature sensor ensures all readings are automatically compensated for temperature variations, delivering consistent, reliable results.

Instruction manual
Preparing Standard Glucose Solutions for Calibration Verification
Procedure:
Place a clean container on an analytical balance and tare to zero
Weigh the required amount of high-purity glucose (CAS #: 50-99-7)
Add distilled or deionized water to reach 100g total weight
For solutions above 60%, stir vigorously and heat to ~40°C (104°F) until dissolved, then cool before use
